I have dual Dell 40's on a 2110 stroker and have never needed a regulator.

From what I have read and been led to believe, part of the appeal of the Dells is that no regulator is necessary. Mine are just set up inline, drivers side to passenger side, nothing in between to regulate.

Are you having a problem or completing a build?

Sounds like he had a secret hidden (oops! not now) anti-theft switch.  Not sure what the ALT one is - guess to the dash light inciter lamp.  That one sound like it could damage the alternator. 

Whatever fuel pump you're running, Bob, is providing the proper fuel pressure without the need for a regulator, and that's great. Other fuel pumps (even the stock mechanical unit- some aftermarket ones are capable of putting out over 7lbs under the right/wrong conditions) need a regulator, and there's no getting around it. I've never heard of Dellortos not being affected by too high fuel pressure (they're not that much different than Webers, as they have fuel inlet valves, do they not?). If they're not affected by fuel pressure like Webers are that's news to me, but then I've never claimed to know everything about these engines (just a whole awful lot!).

@Heritage 2008 (my apologies, I've forgotten your first name)- can you give us the link to the regulator you're looking at?

Hey guys--David from Akron, Ohio

What I have read is that they like 3-3.5 psi and are sensitive to the correct pressure. This regulator is for 1-4 psi. https://www.summitracing.com/oh/parts/hly-12-804   This was a garage find with ZERO literature or info--purchased off widow. Its a 1835 cc is all I know--pulled head to determine that. Not sure if it has a oem cam or not. There had been a electric fuel pump on it at some time but wires were cut and PO put on a mechanical Brazilian pump on it--all I know. Carbs just have been rebuilt so I want to do what I can to prevent issues once its on the road--maybe this weekend and several issues related to a CMC sitting in a garage for 8 years. When I dumped the old gas and tried it when trailered home it spit and choked etc. Had a 050 dizzy in it and after 8 years figured the carb seals/gaskets would be dry and gummed up so--time to sort

Here is what I have done so far. All electrical demons sorted--except determining if the gauges work--they all light up (Vintage white faced for now), rotors turned-bearing cleaned and repacked, new master cylinder and lines, new carter fuel pump, all new hoses, replaced bent oem crank pulley with calibrated pulley, magna spark 2 kit, adjusted valves, Scat Aluminum covers, located very clean oem heater boxes, hideaway exhaust system, shocks, both drive shafts (IRS), installed Setrab cooler with fan, sanded rust free pan and coated with rustoleum--2 coats, butt sag Fb fix including a brace for the rear frame sag.

So back to the regulator--what have others done?????

Harbor freight has a $13 fuel pressure gauge (less 20% off coupon).  FLAPS may have one you can borrow and check it.  It will tell you what the Carter pump is putting out - if its 6-10 PSI then for sure you need regulator.  I would put the regulator off the main feed before the line T's off to separate carbs.

Carter pump says 1-4psi--should I purchase a 6-10 pump and then use the regulator to get it down? This pump was recommended by several SC members so I purchased it/

No, use the Carter pump.  Many have them on here with few, if any complaints.  Most use them without any sort of regulator and they seem fine (including mine).  don't forget - it's a pusher, not a puller.  It has to mount right below the tank in the front.

Remember that there was probably old gas in the fuel line - enough to maybe make it cough and puke when first trying to start it.  Lord knows what else might be messing you up.  Ahhhh.....The Joys of the Madness!

I always use a adjustable  Holley 1 - 4 lb regulator 

Hell if Alan is using it that's good enough for me. So it will be piped in between main line to left carb with gauge screwed into the right side of the regulator.

Used all new line, new tank, cleaned out metal line, metal filter before pump and  after metal pipe by horns before fuel gets to regulator.

So much good advice on this site.

Holley 12-804   1-4 lbs.  get it with the mounting bracket

my setup, carter up front, and holley at the back. I use it as a splitter also :->

Fits nicely on the shelf behind the doghouse and I added a small pressure gauge to help adjust the pressure. The gauge is nice to T-shoot when the engine is not behaving. 

Krusty - nice clean install!  The chrome EMPI fuel pressure regulator always put me off a bit - not sure if chrome, no included mounting bracket or just the EMPI reputation.

Krusty,

I like how you have your breather plumbed. What are you using to go into the block off plate? My carbs are Dells which have the left carb feeding the right carb--I would have to plug the right side of the regulator and then run the gauge in the line from the right carb to the left.

Just look up gas pump block off plate -

I have the block off installed--wanted to know how you are connecting the hose back into the threaded center port--just a brass threaded section?

Yes if I recall well its a 1/4 brass fitting from home depot. Do not quote me on this, its better to bring the block off plate to the store and make sure the fittings are compatible.

The idea is to get the oil to drain back into the engine after over flowing from the valve covers and Oil filler neck.
